Q70: Syndactyly

Syndactyly is a grouping of conditions that form when the digits of the hands or feet, namely fingers and toes, are physically joined together. It develops in the womb, usually caused by irregularities in the fetus' genetic makeup, before the typically separate digits have fully formed. In the affected individuals, this can manifest as webbed skin between the digits, partial fusion, or fully fused digits. The condition may range from relatively minor to severe, with potential to affect the everyday functionality of the individual's hands or feet. However, the progression of tiny, web-like skin between fingers or toes on a child's hand or foot doesn't worsen over time if not attended to. The symptoms are easy to see and diagnose right from birth, often, based on the physical appearance of the child's fingers or toes.
